Finding the Volume of a Bounded Region in 3D Space using Multiple Integrals.

[nameVoid]

vollume bounded by
x+y=4
y^2+4z^2=16

not sure how to set this up

also

I 6y+x dx + y+2x dy
along
(x-2)^2+(y-3)^2=4

also

vollume bounded above by
z=4-4(x^2+y^2)^2
below by
(x^2+y^2)^2-1

What's the whole problem? The plane x + y = 4 and the elliptical cylinder don't define a bounded region.

Have you drawn a sketch of the solid?
